533a5719c5 Completely rewrite the reflow code to correctly handle double width

8149bc3fa6 Be more strict about escape sequences that rename windows or set titles:
ignore any that not valid UTF-8 outright, and for good measure pass the
result through our UTF-8-aware vis(3).

13a0b6bb3f Collect sequences of printable ASCII characters and process them
together instead of handling them one by one. This is significantly
faster. Sequences are terminated when we reach the end of the line, fill
the internal buffer, or a different character is seen by the input
parser (an escape sequence, or UTF-8).

Rather than writing collected sequences out immediately, hold them until
it is necessary (another screen modification, or we consume all
available data). This means we can discard changes that would have no
effect (for example, lines that would just be scrolled off the screen or
cleared). This reduces the total amount of data we write out to the
terminal - not important for fast terminals, but a big help with slow
(like xterm).

7e6c2cb238 Make the selection able to exist independent of the cursor position, so
that it is not affected by scrolling. If MouseDragEnd1Pane is bound to
the new "stop-selection" command:

    bind -Tcopy-mode MouseDragEnd1Pane stop-selection

A selection made with the mouse will stay as it is after button 1 is
released. (It also works bound to a key.)

4179b42424 Add support for BCE (background colour erase). This makes various escape
sequences (notable EL and ED but also IL, DL, ICH, DCH) create blank
cells using the current background colour rather than the default
colour.

On modern systems BCE doesn't really have many benefits, but most other
terminals now support it, some (lazy) applications rely on it, and it is
not hard to include now that we have pane background colours anyway.

Mostly written by Sean Haugh.

2627ab322e Remember the number of lines scrolled into the history (versus cleared
into the history) and when resizing only use scrolled lines and not
cleared lines (which are probably not intended to reappear). From

0f73af876f Don't update cells in each block of data read from a pane immediately,
instead track them as change (dirty) and update them once at the end,
saves much time if repeatedly writing the same cell. Also fix comparison
of cells being equal in a few places (memcmp is not enough).

8a8e2eb04a correctly use HOST_NAME_MAX.
Some notes:
POSIX HOST_NAME_MAX doesn't include the NUL.
POSIX LOGIN_NAME_MAX and TTY_NAME_MAX do include the NUL.

BSD MAXHOSTNAMELEN includes the NUL.  Actually, most of the historical
BSD MAX* defines did include the NUL, except for the historical
mistake of utmp fields without NULs in the string, which directly led
to strncpy..  just showing how error prone this kind of accounting is.
CSRG did right.  Somehow POSIX missed the memo on the concepts of
carefulness and consistancy, and we are still paying the price when
people trip over this.  Of course, glibc is even more amazing (that is
a hint to blackhats)

29d20a55b6 Fix two copy mode problems:
1. In vi mode the selection doesn't include the last character if you
   moved the cursor up or left.
2. In emacs mode the selection includes the last character if you moved
   the cursor to the left.

5e01b6d663 Change the way the grid is stored, previously it was:
- a two-dimensional array of cells;
- a two-dimensional array of utf8 data;
- an array of line lengths.

Now it is a single array of a new struct grid_line each of which represents a
line and containts the length and an array of cells and an array of utf8 data.

This will make it easier to add additional per-line members, such as flags.

ad006bc6b6 When resizing a screen smaller in alternate screen mode, all the lines needed
could be consumed by deleting from the bottom, leaving none to be removed from
the top. In this case, don't call grid_view_delete_lines with ny of 0 as this
is incorrect and causes a bounds check to fatal error if built with -DDEBUG.

359285928b Support "alternate screen" mode (terminfo smcup/rmcup) typically used by full
screen interactive programs to preserve the screen contents. When activated, it
saves a copy of the visible grid and disables scrolling into and resizing out
of the history; when deactivated the visible data is restored and the history
reenabled.
